This are obligatory locations of isolation, situated at random points on the planet. They are mostly lush, island that are uninhabited and cut off from civilization.
And empty grassy waste land with nothing but trees, the surrounding ocean and oh the dangerous wild life. That make this a ' fun ' experience.
This places are usually only accessed by those who are unfortunate that their planes or ships crashed here, or maybe just some hero that flew here for some peace and quiet in secultion (*picks up a green arrow from the island floor* ).
It's an overall entering experience for those who can survive here, One of this island is even said to have some treasure of legends....another is said to have a natural power dampener that prevents it's inhabitants from using any superhuman abilities, while some of the others have real live dinosaurs.
whichever one you land on, I'm sure you've fun trying to survive Mother Nature...Good luck.
